| 中文摘要 | 空间环境是航天器的运行环境,直接关系到航天员和航天器的安全。监测、研究和预报空间环境,是保障航天员、航天器安全的一项重要手段。国内外载人航天工程逐步开展了辐射剂量、带电粒子、轨道大气、等离子体、空间碎片等空间环境参数探测。结合中国载人航天工程发展历程和阶段,着重介绍了中国神舟飞船、目标飞行器的空间环境探测研究情况,提出了后续空间站空间环境探测研究的建议。 |
| 英文摘要 | Around the manned spacecraft s orbits in 300 to 500km altitude,there are all kinds of charged particles,neutral atmosphere,the electromagnetic fields,space debris etc.The space environment fluctuations in a manned spacecraft s orbit can significantly affect the safety of astronauts and spacecraft.The charged particles can cause SEU,SEL and the discharge of spacecraft s surface,even threaten the astronauts safety.The retarded effects of neutral atmosphere make the spacecraft s orbit to descend.Oxygen denndation and oxygen contaminations of atmosphere also affect the solar cell's efficiency and the normal work of then noregnlation materials. To ensure astronauts'safety and normal operations of manned spacecraft, Space Environmental Monitors (SEMs) have been or will be mounted on Chinese manned spacecraft. Detection of SEMs enables ns to understand better the space environment in the manned spacecraft's orbit, and to provide a good space environment service for astronauts and spacecraft. In addition, from the data of SEMs, we will conduct various scientific researches. The development of Chinese manned spacecraft is divided into 3 steps, and SEMs arc used in each step. Space environmental detection in the first step is to have a preliminary understanding of space environment of manned spacecraft's orbits, and to provide the ensuring service for the formal manned flight. The second step considers Chinese feature. The two instruments installed can realize an integrated detection of charged particles and atmospheric environment. The first detector can detect mnlti-direction particles,nnzlti -energy spectrum, radiation dose and LET spectrum. The second detector can monitor atmospheric density,composition and contamination. The following step of space environmental detection pays attention to the safety of astronauts and spacecraft, as well as the new areas of detecting plasma, neutrals, cosmic rays and debris. |
